I have an unlocked US iphone 13. Can I use this iphone in London with an O2 sim card?

I heard someone ask a similar question on here and they were told it won't work because iphones are made for a specific country. However, I thought that if an iphone is unlocked that an O2 sim card should be able to work.

Thank you for your help.
